SPECIFICATION forming part o i Letters Patent No. 455,224,

dated June 30, 1891.

Application filed September 20, 1890. Serial No. 365.595. (No model.)

erence being had to the accompanying draw-v ings, representing av spool embodying my invention, and in which- Figure l is a view ofthe spool. Fig. 2 is a longitudinal central sectional view of one end of the spool; and Fig. 3 is a transverse sectional view on line Y Y, Fig. 2.

Similar letters refer to similar parts in the dierent figures.

My invention relates particularly to that class of spools which are designed for mill use; and it relates especially to the head of the spool and to its attachment to the barrel.

Referring to the drawings, A denotes the barrel, usually made of wood and bored at each end, forming a concentric chamber B,

extending a short distance into the barreh VVthin this chamber a wooden plug C is litted, provided with a series of annular grooves C. The outer end of this plug extends beyond the end of the barrel B at D, and is made slightly smaller in diameter to receive a metallic ferrule E, the end of the ferruleE abutting against the. shoulder a in ,the Yplug C, and the outer end of the ferrule is closed atE with a hole E2, concentric with the ferrule and of the proper size to receive the spindle N, forming the gudgeo-n to the spool. The head G of the spool is made of an elastic metal, like spring-steel, and consists of a circular disk with a concentric hole at H Iitting the periphery of the metallic ferrnle E and resting against the end of the barrelA.

The outer edge of the head G is turned over,

forming a iiange G', which is curved invsubstantially'semicircular form in its cross-section, as represented in Fig. 2, the edge G2 of the curved iange being brought into, sub- .stantially a plane parallel with that of the disk of sheet metal forming the head itself. This gives a round or semicircular edge to the edge of the head, and by turning the edge at G2 into a plane parallel with the head itself Yunscrewing it upon the spindle N.

the' edge of the head is stienedto resist any blows upon the edge of the head caused by dropping the spools upon the floor or otherwise. The head of the spool is held in place upon the end of the barrel by means of a nut J, which is driven into the chamber B before the insertion of the wooden plug C, the corners of the nut entering the wall of the chamber, as represented at J J in Fig. 3, to prevent the uut from turning in the chamber B.

The plug C has a concentric hole coincident with the lscrew-threaded vhole in the nut J, and also with the hole E2 in the ferrule E, and a concave washer L is placed upon the head G, with its edge resting against the head. The concave Washer L has a screw-threaded Ahole L in the center, and through the screwthreaded hole I place a screw-threaded spindle N, the end of the spindle passing through the nut J. The outer end of the spindle VN is left plain, and the washer L is screwed against the plain section of the spindle, so that the Washer L cannot be loosened 'llily T e spindle N is screwed into the nut J, bringing the nut J firmly against th'e inner end of the plug C and drawing the edge of the concave washer irmly upon the head G. The spindle N is then held from turning by means of a pin O driven through a. hole in the barrel and the end of the spindle N, as represented in Fig. 2. The plug C is covered with a coating of glue or adhesive material previous to its being driven into the chamber B, and the grooves C serve to retain the glue that would be scraped from the surface of the plug by the operation of driving the plug into the chamber. The shoulder a should be liush with the end of the barrel or brought slightly within the barrel, in order to secure a bearing' of the inner edge of the head Gupon the me- .tallic ferrule E, so that 'the edge'of the head will not abrade the wood of the plug C, and the hole E in lthe ferrule is made to closely fit the spindle N and hold the spindle from contact with the interior of the plug, as it is similarly held at its inner end by the nut J.

An advantange is also gained in employing a spindle Nwhich is screw-threaded throughout nearly its entire length and employing roo with the screw-threaded spindle a screwthreaded washer L, as the nut J and washer L act as check-nuts one for the other.

lVhat I claim as of my invention, and desire to secure by Letters Patent, is

`1. The combination, with the barrel of a spool having a concentric chamber at its end,

of a nut held in said ehalnber, a head resting i against the end of the barrel, a screw-threaded concave washer bearing against the outer surface of lthe head, and a screw-threaded spindle passing through said washer and entering said nut, substantially as described.

2. The combination,with the barrel of a spool having a concentric chamber at its end, of a nut held in said chamber, ahollow plug placed in said chamber by which said nut is retained in position, the end ofsaid plug projecting beyond the end of said barrel, ametallic ring or ferrule inclosing the projecting,r end ot said plug, a head held concentrically on the projecting ond of said plug, a screw-threaded washer bearing againstthe outer surface of the head, and a screw-threaded spindle passing through sai'd washer and entering said nut, substantially as described.

3. The combination, with a spool having a concentric chamber at its end, of a nut held in said chamber, a hollow block placed in said chamber, whereby the nut is retained in its position, said plug having its end projecting beyond the barrel of the spool, a metallic ring or washer inclosing said projecting end of the plug, a metallic head placed concentrically upon the projecting end of said plug and having a flanged edge turned over so as to bring the edge of the ange parallel with the plane of the head, a washer resting upon the outer surface of said head, and a bolt passing through said washer and said hollow plug and entering the nut llel'd in the concentric chamber of the barrel, substantially as described.

4:. The combination, with the barrel of a spool having a concentric chamber, of a nut held in said chamber, a hollow plug placed in said chamber, whereby said nut is held in position, said plug having its end projecting beyond the end of thc barrel, a metallic head placed concentrically upon the projecting end of said plug and having' a flanged edge, a metallic ring or ferrule interposed between the edge of said head and the projecting end of said plug, a washer resting against the outer surface of said head, a screwthreaded spin-` dle passing through said Washer and said hollow plug and entering the nut held in the concentric chamber of the barrel, and a retaining-pin passing through said barrel and said screw-threaded spindle, whereby it is held from rotation, substantially as described.

A5. The combination, with the barrel of a spool havinga concentric chamber at its end, of a nut held in said chamber, with its corners engaging the Walls of said chamber, whereby said nut is held from rotating, a hollow plug placed in said chamber, by which said nut is held in position, said plug having its end projecting beyond the end of said barrel, a metallic head held concentrically upon the projecting end of said plug, a washer resting against the outside of said head, and a screw-threaded spindle passing through said Washer and said hollow plug and entering the nut held in said concentric chamber, whereby said Washer is drawn against said head, substantially as described.

G. The combination, with the barrel of a spool having a concentric chamber at its end and a nut held in said chamber, of a hollow plug held in said chamber and projecting beyond the end of said barrel, a head resting against the end of said barrel and held concentrically upon the projecting end of said plug, a concave washer extending over and covering the projecting end of said plug, with its edge resting upon the outer side of said head, and a screw-threaded spindle passing through said hollow` plug and entering the nut held in said concentric chamber and engaging -said concave washer, whereby it is drawn firmly against thc head, substantially as describe l Signed this 18th day of September, 1890.
